[A Case of Suspected Non-Occlusive Mesenteric Ischemia following Neoadjuvant Chemotherapy for Esophageal Cancer with an Extremely Poor Prognosis].

Non-occlusive mesenteric ischemia(NOMI)is defined as intestinal ischemia or necrosis with patency of the mesenteric arteries. Here, we report a case of suspected NOMI following neoadjuvant chemotherapy for esophageal cancer with an extremely poor prognosis. A 79-year-old man complained of weight loss and vomiting. Esophagogastroduodenoscopy revealed a tumor extending from the lower intrathoracic esophagus to the gastric cardia. He was diagnosed with esophageal cancer(small cell neuroendocrine carcinoma, T3(AD)N0M0, cStage Ⅱ)accordingly. He received cisplatin and etoposide as neoadjuvant chemotherapy. Tube feeding was initiated due to tumor stenosis. His weight increased rapidly by more than 8 kg on the second day of treatment. He did not display any signs of heart failure, and so continued chemotherapy in conjunction with diuretics. Upon completion of chemotherapy, his continued use of diuretics gradually reduced his weight. On day 7, the patient complained of nausea and experienced a decrease in blood pressure. Bicarbonate Ringer's solution was administered intravenously, but the patient lost consciousness after 3 hours. Plain computed tomography revealed massive gas collections in the portal vein, tumor wall, stomach, and ascending colon. NOMI was strongly suspected. His condition continued to deteriorate, until his demise several hours later. Here, we present the above-mentioned case and discuss the relevant literature.

Association Among End-Of-Life Discussions, Cancer Patients' Quality of Life at End of Life, and Bereaved Families' Mental Health.

End-of-life discussions are essential for patients with advanced cancer, but there is little evidence about whether these discussions affect general ward patients and family outcomes. We investigated the status of end-of-life discussions and associated factors and their effects on patients' quality of death and their families' mental health. Participants in this retrospective cross-sectional observational study were 119 bereaved family members. Data were collected through a survey that included questions on the timing of end-of-life discussions, quality of palliative care, quality of patient death, and depression and grief felt by the families. Approximately 64% of the bereaved family members participated in end-of-life discussions between the patient and the attending physician, and 55% of these discussions took place within a month before death. End-of-life discussions were associated with the patients' prognostic perception as "incurable, though there is hope for a cure" and "patients' experience with end-of-life discussions with family before cancer." There was a small decrease in depression and grief for families of patients who had end-of-life discussions. Those who did not have end-of-life discussions reported lower quality of end-of-life care.

Laparoscopic versus open surgery for complicated appendicitis in adults: a randomized controlled trial.

BACKGROUND: The aim of this study was to assess whether laparoscopic appendectomy (LA) for complicated appendicitis (CA) effectively reduces the incidence of postoperative complications and improves various measurements of postoperative recovery in adults compared with open appendectomy (OA). METHODS: This single-center, randomized controlled trial was performed in the Nagoya Daini Red Cross Hospital. Patients diagnosed as having CA with peritonitis or abscess formation were eligible to participate and were randomly assigned to an LA group or an OA group. The primary study outcome was development of infectious complications, especially surgical site infection (SSI), within 30 days of surgery. RESULTS: Between October 2008 and August 2014, 81 patients were enrolled and randomly assigned with a 1:1 allocation ratio (42, LA; 39, OA). All were eligible for study of the primary endpoint. Groups were well balanced in terms of patient characteristics and preoperative levels of C-reactive protein. SSI occurred in 14 LA group patients (33.3 %) and in 10 OA group patients (25.6 %) (OR 1.450, 95 % CI 0.553-3.800; p = 0.476). Overall, the rate of postoperative complications, including incisional or organ/space SSI and stump leakage, did not differ significantly between groups. No significant differences between groups were found in hospital stay, duration of drainage, analgesic use, or parameters for postoperative recovery except days to walking. CONCLUSION: These results suggested that LA for CA is safe and feasible, while the distinguishing benefit of LA was not validated in this clinical trial.

Laparoscopic subtotal cholecystectomy for severe cholecystitis.

BACKGROUND: The concept of laparoscopic subtotal cholecystectomy (LSC), without approaching Calot's triangle to avoid both laparotomy and serious complications, is not widely accepted. In this study, we evaluated the outcomes of LSC for severe cholecystitis when dissection of the cystic duct and cystic artery is hazardous. METHODS: From January 2004 to December 2013, 110 consecutive patients who underwent LSC without ligation of the cystic duct and vessels were enrolled in this retrospective study. Their clinical records, including operative records and outcomes, had been entered into a prospectively maintained database and were analyzed. RESULTS: The mean operating time and blood loss were 121 min and 33.8 ml, respectively. All LSCs were completed without conversion to an open procedure. No injuries to the bile duct or vessels were experienced. Postoperative complications occurred in ten (9.1%) patients, including subhepatic hematoma in 3, bile leakage in 3, and subhepatic abscess in 1. Patients recovered from complications without requiring re-operation. During follow-up periods (mean 30.7 months), symptomatic biliary stone diseases relapsed in three patients (2.7%) and were successfully treated by endoscopic management. CONCLUSIONS: LSC without an attempt to dissect Calot's triangle is a safe and feasible procedure that can avoid conversion to laparotomy.

The determination of bile leakage in complex hepatectomy based on the guidelines of the International Study Group of Liver Surgery.

BACKGROUND: The International Study Group of Liver Surgery (ISGLS) has defined bile leakage as a drain fluid-to-serum total bilirubin concentration (TBC) ratio (the bilirubin ratio) ≥ 3.0. The aim of the present study was to determine the clinical significance of this definition, and to outline characteristics of bile leakage in complex hepatectomy. METHODS: The TBCs of the serum and drain fluid were measured on postoperative days (POD) 1, 3, and 7 in 241 patients who had undergone hepatobiliary resection. The validation of the bilirubin ratio and predictors of bile leakage were retrospectively assessed. RESULTS: Grade A, B, or C bile leakage was found in 23 (9.5 %), 66 (27.4 %), and 0 patients, respectively. The median duration of drainage was 27 days in grade B bile leakage. The sensitivity and specificity of the bilirubin ratio for detecting grade B bile leakage were 59 and 87 %, respectively. The area under the receiver operating characteristics curve of the drain fluid TBC on POD 3 had the highest predictive value: 68 % sensitivity and 76 % specificity for a drain fluid TBC of 3.7 mg/dL. The multivariate analysis demonstrated that operative time, left trisectionectomy, bilirubin ratio, and TBC of the drain fluid on POD 3 were independent predictors of grade B bile leakage. CONCLUSIONS: In complex hepatectomy, bile leakage develops most frequently after left trisectionectomy and often results in a refractory clinical course. The ISGLS biochemical definition is valid, and a combination of bilirubin ratio and drain fluid TBC may enhance risk prediction for grade B bile leakage.

Synchronous rectal and esophageal cancer treated with chemotherapy followed by two-stage resection.

We report a case of 61-year-old male who had synchronous advanced rectal cancer involving the urinary bladder massively associated with multiple liver metastases, and esophageal cancer successfully treated by neoadjuvant chemotherapy followed by two-stage resection. Although complete resection of each of the lesions was considered possible by performing anterior pelvic exenteration, liver resection, and esophagectomy, it might be impossible for the patient to endure the stress of all of these operative procedures at once. Therefore, we planned to perform staged treatment with prioritizing consideration. First, we instituted chemotherapy with the FOLFOX (oxaliplatin + fluorouracil + leucovorin) plus cetuximab regimen, which could adequately control both rectal and esophageal cancer. After 6 cycles of chemotherapy, high anterior resection combined with cystoprostatectomy and lateral segmentectomy plus partial hepatectomy was performed followed by staged esophagectomy with three-field lymph node dissection. It was possible to use oxaliplatin and cetuximab safely as neoadjuvant therapy not only for advanced rectal cancer but for esophageal cancer, and it was effective.

Clinical and oncologic safety of laparoscopic surgery for obstructive left colorectal cancer following transanal endoscopic tube decompression.

BACKGROUND: Little information has been available concerning the safety of laparoscopic resection of obstructive colorectal cancer after transanal endoscopic tube decompression (TETD). The aim of this study was to assess the short- and long-term outcomes of laparoscopic surgery following TETD for such advanced colorectal cancer. METHODS: A retrospective review was performed of 40 patients with obstructive left colorectal cancer whose distended bowels were treated with TETD before laparoscopic surgery, between January 2001 and March 2011 (TETD group). The elective surgery resulted in potentially curative resection of the tumor in all cases. Their clinical records were compared to those of 80 matched controls with nonobstructive left colorectal cancer resected laparoscopically during the same period (control group). RESULTS: Operative time, blood loss, and the rate of conversion to laparotomy were comparable between the two groups. There were no significant between-group differences in morbidity rates. Five-year overall survival rates in the TETD and control groups were 71.9 and 75.4%, respectively, with no statistical difference. Disease-free survival rates after 5 years were also similar (TETD group, 64.5% vs. control group, 66.3%). There were no significant differences between the two groups in recurrence rates and patterns. CONCLUSION: These results suggest that laparoscopic surgery following TETD is clinically and oncologically safe and could be a treatment of choice for obstructive left colorectal cancer.

Locally recurrent rectal cancer successfully treated by total pelvic exenteration with combined ischiopubic rami resection: report of a case.

A combined ischiopubic rami resection is extremely rare in the field of gastroenterologic surgery. We report a case of a locally recurrent rectal cancer that was successfully treated by total pelvic exenteration with combined ischiopubic rami resection. A 58-year-old male with locally recurrent rectal cancer and liver metastases was referred to our hospital. Computed tomography and magnetic resonance imaging showed a perineal tumor, which had invaded the prostate, urethra, and obturator internus muscle, and two liver metastases. Because the perineal tumor was very close to the dorsal vein complex and the pubic symphysis, it was considered difficult to approach and divide the dorsal vein complex, and still retain oncologic safety. To achieve R0 resection, total pelvic exenteration with ischiopubic rami resection, total emasculation and partial liver resection were performed. Pathological examination revealed that surgical margins were negative for cancer cells. Although reconstruction of the pelvic ring was not performed, his ambulatory function had recovered to an almost normal status at 6 months after the operation.
